FEEDING ATTACHMENT.

Application filed April 4,

To all 'w/z am it may concern.

e it known that I, LAwRnNon B. GRAS- nnnonn, a citizen of the United States, residing at the city of Richmond, in the State of Virginia, have invented certain new and useful Improvements in Feeding Attachments, of which the following is a specification. I

This invention relates to feeding attachments for roll holders used in stores for supplying wrapping paper in sheets of suitable length as wanted; and it consists of devices supported by the blade and its arms and adapted to feed the end portion of the paper beyond the blade after a sheet has been torn from the roll against the blade, said devices being provided with revoluble cams for raising the and partially revolving the roll.

In the drawings, Figure 1 is an end view of the upper part of a paper roll holder provided with a feed attachment according to this invention. Fig. 2 is a front view of the same. Fig. 3 is an end view of the attachment shown in Fig. 2, but drawn to a larger scale, and showing the cam engaging with the paper. Fig. 4 is a front view of the device as shown in Fig. 3.

The attachment may be applied to many forms of roll holders, both horizontal and vertical. In the example shown, the roll of paper 6 is horizontal. and it is journaled in a frame 7. A blade 8 is secured to arms 9. and bears on the periphery of the roll.

pivoted to the frame, by pins against the The arms are 10, and the paper is torn off bottom edge of the blade.

The rollhas to be revolved a little after the paper has been torn off, so that the loose end of the paper can be grasped, and the feeding attachment enables this to be done with facility.

Brackets 12 are secured to the blade, or to its arms, and have bearings-14 in which feeder shaft 15 is journaled. This shaft has a knob orhandle 16. atone end or at each end. for revolving it by hand. Two cams or roller segments 18 are secured on the shaft 15. and may be covered with india rubber 19. or other similar material. A brake spring 20 is secured. to one of the brackets. and its free end bears on a friction brake roll 21 secured on the shaft, and which may be the hub of one of the cams. Each cam may have a similar brake, if desired... This spring normally holds the cams blade clear of the paper pressed on the roll when the cams 1922. Serial No. 549,537.

stationary when they are clear ofthe paper, and the roll-21 formed like the tooth of a ratchet toothed wheel, and which normally bears on the end of the spring, and prevents the shaft from being revolved in the wrong direction.

lVhen the shaft .is revolved in the direction of the curved arrow in Fig. 3, the cams engage with the paper, and partially revolve the roll so that the loose end 24 of the paper preferably has a stop 22' i can be grasped, and they raise the blade I and hold it clear of the paper as long as the roll is being revolved by them.

What I claimis:

1. The combination, porting a roll, and a frame and adapted to brackets which -move pivotally with the blade, a feed shaft journaled in the brackets, and cams secured on the shaft and adapted to revolve the roll intermittently, the said cams operating to raise the bladeand hold it clear of the roll while the roll is being revolved by them, and said blade being pressed on the roll when the cams are out of engagement with the roll.

2. The combination, with a frame for supporting a roll, and a blade pivoted to the frame and adapted to bear on the roll; of brackets which move pivotally with the blade, a feed shaft iournaled in the brackets, cams secured on the shaft and adapted to intermittently, the said andhold blade pivoted to the revolve the roll cams operating to raise the blade it clear of the roll while the roll revolved by them. and said blade being of engagement with the roll, and a friction brake operating to prevent the premature revolution of the cams.

e The combination, with a frame for of brackets which move pivotally with the blade, a feed shaft jonrnaled' in the brackets, cams secured on the shaft and adapted to revolve the roll intermittently, the said cams operating to raise the blade and hold it clear of the roll while the roll is being revolved by them, and said blade being; pressed on the roll when the cams are out of engagement with the roll, a friction brake roll secured on the said shaft and having a projecting stop at its periphery, and a brake spring secured to one of the said brackets and bearing on the said brake roll and normally preventing it from being revolved baekwardly when the spring is in contact With the said stop.

In testimony whereof I have affixed my signature.
